MACHINE FOR MAKING WIRE HEDDLES.

SPECIFICATION forming part of Letters Patent No. 403,879, dated May 21, 1889. Application filed August 27,1888. Serial No. 283,824. (No model.) Patented in France May 3, 1888, No. 190,347.

To all whom it may concern:

Be it known that I, EMMANUEL ESBRAYAT, of Lyons, in the Republic of France,-have invented certain new and usefullmprovements in Machines for Making WVire Heddles, (which. have been patented to me in France, No. 190,347, under date of May 3, 1888,) of which the following is a specification.

This invention relates to an improved machine for making wire heddles of that class in which the warp-eye is made integral with the shank of the heddle and connected by twisted shanks with the heddle-bar eyes at the ends, said machine being adapted for producing said heddles in a quick and uniform manner; and the invention consists of a machine for making wire heddles, in which the wire blank is stretched on studs or posts of guided and spring-actuated slide-plates, and in which the twisted shanks are produced by a fixed spindle secured into a longitudinallyreoessed rotary pinion located in line with the posts. Near one of the stretching studs or posts is arranged a rotary and springcushioned spindle having a hook-shaped inner end for taking hold of and twisting the ends of the wire blank, and a cutting device for cutting off said twisted ends to uniform length.

In the accompanying drawings, Figure 1 represents a side view of a wire heddle of the usual well-known construction, which is to be made by my improved machine. Fig. 2 is a vertical longitudinal section of my improved machine for making wire heddles; Fig. 3, a plan view of the same; Fig. 4, a detail end view of the rotary pinion and the spindle for forming the warp-eye; and Figs. 5 and 6 are details showing the stretching of a single or double wire blank on the posts preparatory to twisting the blank.

Similar letters of reference indicate corresponding parts.

The machine consists of a bed-frame, A, on which are arranged longitudinal ways B, on which are guided slide-plates O C, to each of which is applied a vertical stud or post, D, having rounded-01f edges, which studs serve for forming the heddle-bar eyes of the heddle. The slide-plates C C are movable on the ways B B between fixed abutments E and F, which control the extent of motion of the slide-plates O 0 when the wire blank of the heddle is being twisted. The slide-plates O C are connected by spiral springs C. 0, attached to pins d cl at the under side of the slide-plates C and of the outer abutments F F, so as to be moved toward said abutments when no tension is exerted on the studs or posts D D. Midway between the slide-plates C C the ways B B are recessed transversely and provided with a fixed ring-shaped bearing, B, that supports the journals of a pinion, G, so that the latter can rotate in said bearings.

The pinion G and its ring-shaped bearing B are provided with a radial recess, g, that extends from the circumference toward and slightly beyond the center of the pinion, the pinion being provided in said recess with a fixed and pointed spindle, N, which is retained in the pinion by a setrscrew, h, as shown in 2, said spindle being of rhombic or other cross-section and serving to form the warpeye of the heddle. The pinion G is rotated by a cog-wheel, G, of larger diameter, the shaft 2 of which is rotated by a crank-handle, G rotary motion being also transmitted from said shaft byintermediate gearings, t" 1? 1 to a spindle, Z, which spindle is supported in line with the studs or posts D D and the spindle of the pinion G. To the spindle Z is applied a fixed collar, i between which and the supporting-standard of the spindle is interposed a spiral spring, that serves to cushion the spindle against the tension exerted on the same by the wire blank in forming the heddle. The gear-wheel i is made wide enough to provide for the mot-ion of the spindle without getting out of mesh with the gear-wheel t The end of the spindle Z is made hookshaped and serves to engage the ends of the wire blank from which the heddle is formed, as shown in Figs. 5 and 6, so as to twist said ends together simultaneously with the twisting of the shanks of the heddle by the opera tion of the machine. Near the end of the spindle and transversely theretois arranged a fixed cutter, L, and a pivoted cutting-knife, L, which serve to cut oif or trim the twisted end of the wire heddle when the twisting of the same is accomplished, the cutting device L L being clearly shown in Figs. 2 and 3.

The machine is operated as follows: Wire blanks of the length required for making a heddle are first cut and then doubled up and placed in position around the posts D D and on the hooked end of the spindle Z, as shown in Figs. 5 and 6. The recess of the pinion G is then placed in line with the studs D D, so that the wire blank can be introduced in the recess at both sides of the spindle h. The ends of the Wire blank are then placed over the hook of the spindleil, after which the machine is set in motion by turning the handcrank G This produces the turning of the pinion G and its spindle h, and produces the twisting of the wire blank between the spindle and the studs D D, forming thereby' the warp-eye on the spindle, the twisted shanks, and the shaped heddle-bar eyes. Dnring the twisting motion of the wire the sliderplates O C are slowly moved forward until they are t pp d b h ien a u ment E, aft w ich t e opera n of h machine is. int rrupted. Simultaneously with the twisting of the shanks of the heddle at both sides of the Wa p-ey he ends Qt the W r blank are else.

t iste together by h etet ng p ndle Z This twisted end is then trimmed by the cutting device ,L, L, after which the heddle is removed from the studs D andspindle h. The slide-plates 0 Q, as well as the spindle Z, are then returned by their springs to their nor mal position. The springs of the slide-plates O, as well as the springs of the spindle Z, are both for the same purposen-amely, for compensating for the shortening of the wire blank during the twisting operation, while keeping the blank sufficiently tight for the purpose'of producing the required twist. Sometimes double-wire heddles made of two blanks are desired to be produced, in which case the two wire blanks are placed on the studs D and on the spindle of the pinion G in the same manner as before described for one blank; but in this case a small disk-shaped washer, 713, (shown in Fig, 6,) is used, which is placed over the spindle intermediately between the blanks, so as to separate the second blank from the first blank and prevent the intertwisting of the wires at the warp-eye. On removing the heddle the washer is removed from the adjoining eyes of the heddle.

Having thus de s iribed my invention, I claim as new and desire to secure by Letters Patent- 1. In a machine for making wire heddles,

posts, fixed abutments at each side of said.

slide-plates, a rotary pinion located.- intermediately between said slide-plates, said pinion being provided with a radial recess and a fixed spindle in said recess, and a rotary and spring-actuated spindle having a hook-shaped end in line with said lugs and central spindle, sub n ially et er h- 3- hecembieafien f lens ld nal y-s'u.i e
